Image of the Kerr-Newman black hole surrounded by a thin accretion disk
Sen Guo, Yu-Xiang Huang, En-Wei Liang +3
The image of a Kerr-Newman (KN) black hole (BH) surrounded by a thin accretion disk is derived. By employing elliptic integrals and ray-tracing methods, we analyze photon trajector…
Radio Pulsar B095008: Radiation in Magnetosphere and Sparks above Surface
Zhengli Wang, Jiguang Lu, Jinchen Jiang +6
We observed the nearby 100-duty-cycle radio pulsar B0950+08 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We obtained the polarization profile for its…
A Comprehensive Analysis of Insight-HXMT Gamma-Ray Burst Data. I. Power Density Spectrum
Zi-Min Zhou, Xiang-Gao Wang, En-Wei Liang +7
Power Density Spectrum (PDS) is one of the powerful tools to study light curves of gamma-ray bursts (GRBs). We show the average PDS and individual PDS analysis with {\it Hard X-ray…
Potential Chromospheric Evaporation in A M-dwarf's Flare Triggered by Einstein Probe Mission
J. Wang, X. Mao, C. Gao +12
Although flares from late-type main-sequence stars have been frequently detected in multi-wavelength, the associated dynamical process has been rarely reported so far. Here, we rep…
